Volatility might be defined simply as the daily gyrations of a given market (eg CL,ES,YM). Therefore you can do better than 'prediction', you can establish the datasets of the metrics and parameters of that market.

As I have a professional background in futures, I have for some five years at ET pointed to where the money is in a market, which is in the gyrations. Therefore you can take it as proven that very few, if any, coming through ET will ever want to make themselves rich because they do any manner of things other than adopt a methodology to try and take the money where it arises in a market, open through to close, day in and day out.
